Berry’s petition for post-conviction relief.was. denied by the trial court. Before his robbery conviction, he had entered a special plea of insanity. His plea averred that he had suffered from chronic alcoholism and emotional instability at the time of the robbery. The State offered observational evidence of Berry’s demeanor during and after the robbery. In the opinion of court-appointed medical experts, Berry was “legally sane” when the robbery was committed. The trial court gave the jury the following instruction:
“The law presumes that a man is of sound mind until there is some evidence to the contrary. In prosecutions for offenses against the law, an accused is entitled to an acquittal if the evidence engenders a reasonable doubt as to his mental incapacity at the time the alleged offense is charged to have been committed. Evidence rebutting or tending to rebut the presumption of sanity need not, to entitle the defendant to an acquittal, preponderate in favor of the accused. It will be sufficient if, when considered in connection with all of the evidence introduced in this case, it raises in your mind a reasonable doubt.”
Berry’s robbery conviction was affirmed by the Indiana Supreme Court.
Berry
v.
State
(1968),
We consider the retroactive application of the new rule, and we conclude that the new rule can not be retroactively applied. The trial court did not err when it denied Berry’s petition for post-conviction relief from the robbery conviction. We affirm.
I.
Changing the Rule
Berry’s appeal to the Indiana Supreme Court raised his contention that the trial court’s presumption of sanity in
*628
struction constituted prejudicial'error and required the reversal of his conviction. He argued that the introduction' of any admissible proof tending to demonstrate legal insanity was sufficient to wholly neutralize the presumption of sanity and rendered the presumption an improper subject for jury consideration. In
Berry
v.
State
(1968),
Approximately four years later, the Supreme Court had an occasion to reconsider its decision in
Berry
v.
State, supra.
In
Young
v.
State
(1972),
In his post-conviction petition, Berry contends that the Supreme Court’s subsequent decision in the Young case requires the reversal of his conviction. There is no doubt that the record of Berry’s trial discloses a clear violation of the Young rule. In light of Berry’s introduction of competent evidence in support of his insanity defense, the Young rule would have prohibited the trial court from instructing the jury as to the legal presumption of sanity. But, Berry’s assertion that the Young decision requires a reversal of his conviction, at a trial which occurred some four years before Young *629 was decided, is not dispositive of this appeal. The majority opinion in Young was silent on the question of whether the new rule adopted by the Supreme Court was to be applied retroactively to criminal convictions finalized prior to the effective date of the Young decision, or was to be limited to a prospective application. Thus, this Court must decide whether the Young rule governs appeals in cases which, like the one before us, reached trial prior to the date of Young.
II.
Retroactive Application
The Supreme Court’s decision in
Young
was clearly based upon non-constitutional policy considerations; the majority opinion contains no reference to either federal or state constitutional provisions. As a matter of federal constitutional law, it has been held that a State may validly impose on a criminal defendant the burden of proof on the issue of legal sanity.
Leland
v.
Oregon
(1952),
In discussing the issue of retroactivity, the United States Supreme Court has referred to a three prong test, which focuses upon: (1) the purpose of the new rule of law (2) reliance by the courts for authority on the old rule; and (.3) the effect of retroactive application on the system of criminal justice.- Indiana Supreme Court decisions concerning the retroactivity of new constitutional rules of criminal pro
*630
cedure have employed an identical analytic framework.
See, e.g., Enlow
v.
State
(1973),
The following discussion of the countervailing considerations for and against either retroactivity or prospectivity demonstrates the nature of the problem confronting us in deciding the retroactivity question. When a choice is acknowledged between giving some retroactive effect, or none at all, a line should be drawn between the rules which are to be afforded such retroactive application and those which are not, accompanied by some realistic basis for the distinction. Therefore, in arriving at some principled basis for making such a distinction, it is necessary to explore existing case law as to the appropriate policy grounds which govern the issue of retroactivity.
Once the United States Supreme Court had established that the Constitution neither prohibited nor required retroactive application of new criminal procedural guarantees, some method of analysis was needed to determine questions in any given case. The Court’s response to this need has become known as the
Linkletter-Tehan
test.
See, e.g., Tehan
v.
United States ex rel. Shott
(1966),
A. Old Rule Reliance
The reliance consideration of the Linkletter-Tehan test involves the reliance of law enforcement officers as well as the reliance of the judicial system upon the operational finality of the old rule. Reliance of law enforcement officers and of the judicial system are interrelated, since there would be no reliance by law enforcement officers if the courts had not, either explicitly or tacitly, approved law enforcement procedures by judicial decision. Furthermore, since reliance also includes judicial reliance, it is closely aligned with burdening the administration of justice, another consideration in the Link-letter-Tehan test.
The reliance consideration upon which the Court has focused in applying the
Linkletter-Tehan
test is viewed as either being justified or unjustified and extensive or slight.
See e.g., Roberts
the judicial system are interrelated, since there would be no reliance by law enforcement officers if the courts had not, either v.
Russell
(1968),
B. Burden on the Administration of Justice
Another important and related factor in determining the retroactivity question is the burden that retroactivity is likely to impose on the courts. Retroactive application of a new rule could cause a great burden on the administration of justice by increasing the volume of retrials raised by post-conviction relief or by reversal of convictions on direct appeal. The rule laid down in
Mapp
v.
Ohio
(1961),
C. The Purpose of the Rule
When the Supreme Court of the United States has been confronted with the retroactivity question, its first, and *633 perhaps most important consideration, has been whether the purpose of the new rule can be practically accomplished by retroactive application. The Court has analyzed the purpose of the new rule in terms of two key aspects of procedural due process. The first aspect is that of insuring the reliability of the guilt determining process. The second aspect is that of insuring respect for individual rights and liberties.
If the primary purpose to be advanced is the reliability of the guilt determining process, the Court has begun its analysis by emphasizing the fundamental importance of the protections in the criminal justice system aimed at safeguarding the liberty and freedom of the criminal defendant.
See, e.g., Johnson
v.
New Jersey
(1966),
When the primary purpose of the new procedural rule has been to enhance individual freedom by the enforcement of constitutional protections, the Supreme Court’s analysis has been somewhat divergent. Generally, the Court has reasoned that because retroactive application of a new rule can not
*634
operate to rectify a prior infringement of individual freedom, such retroactive application can not be justified.
See, e.g., Johnson
v.
New Jersey
(1966),
D. Other Factors
A case-by-case determination of whether a new rule of criminal procedure should be retroactively applied may entail other decisional factors which have not been discussed in the reported cases. This Court may wish to consider whether the purpose of the new rule was to cure a serious and prejudicial defect in the fact-finding process, or whether the new rule was designed to correct a minor imbalance in trial practice. In this context, it may be appropriate to ask: Did the prior erroneous rule seriously impair the reliability of the guilt-determining process? If there is a strong probability that the use of the new procedural standard could materially affect the result of a retrial, this circumstance would indicate that the new rule should be accorded retroactive application. On the other hand, if the new rule’s application on retrial would not significantly alter the nature and amount of evidence to be considered by the trier-of-fact, then it might be concluded that the collateral burdens created by retroactive application outweigh the possible benefits of a redetermination of guilt.
Another factor might be the nature of the new procedural rule in the context of judicial review of past convictions. Some procedural rules govern aspects of trial practice which have evolved into hard and fast standards. For example, an in-custody confession obtained in the absence of prior Miranda warnings is a per se procedural violation. A reviewing court *635 could immediately recognize and correct such a procedural error without considering the specific factual circumstances surrounding the invalid confession. In contrast, other procedural rules are of a fact-sensitive nature; a judicial determination as to an alleged infringement of this type of procedural safeguard calls for a detailed examination of all the facts relevant to the rule’s application. Paradigms of this procedural rule arise in the area of Fourth Amendment restrictions on the law of search and seizure. This simple distinction among the rules of criminal procedure may have a significant impact on the retroactivity issue.
In reaching a decision as to the propriety of a retroactive application of a new rule, the Court should make some practical assessment of the probable result in terms of both the ease of applying the new rule to past convictions, and the number of retrials which would likely result from allowing prisoners to raise the new rule as a ground for reversal. A new procedural rule which could be utilized as a standard of review irrespective of the particular factual circumstances of each prior conviction would be more deserving of retroactive application, since the court could be assured that a significant number of petitioners, whose convictions were tainted by the old procedural defect, would be entitled to new trials. On the other hand, retroactive application of a procedural rule of a fact-sensitive nature might result in the invalidation of only a negligible number of prior convictions and would entail a much greater expenditure of judicial resources in passing upon the merits of the necessary post-conviction relief petitions.
III.
Conclusion
The Young rule was designed to improve the reliability of the guilt determining process. The Young majority recognized that it was improper and prejudicial to instruct a jury *636 as to the existence of the legal presumption of sanity after a defendant’s competent proof on the issue of insanity had wholly negated the legal significance of the presumption. Thus, the purpose of the Young rule was to prevent a jury from weighing the legal presumption of sanity to the State’s advantage in cases where the presumption was without evidentiary value. While the Young opinion would appear to indicate that the mere instruction of the jury as to the presumption of sanity is per se reversible error when the defendant satisfies his burden of producing evidence on the issue of insanity, we do not feel that the cumulative improvement of reliability brought about by Young justifies its retroactive application in this case. The instruction, while defective under Young, nevertheless did attempt to advise the jury that they should acquit the defendant by reason of insanity unless they found from a consideration of all the evidence that he was sane beyond a reasonable doubt. Furthermore, the State adduced some answering proof on the issue of insanity at Berry’s trial. It, therefore, does not appear that the trial court’s improper instruction seriously impaired the reliability of the jury’s determination of guilt. Moreover, we believe that jury determinations in those cases tried prior to Young where the State adduced some evidence of legal sanity will not be subject to serious doubt as to reliability, even though the verdict was tainted by the jury’s improper consideration of the presumption of sanity. We would deny retroactive application of the Young rule to those cases.
Prior judicial reliance on the Berry rule, which the Young decision discredited, was both justified and extensive. It should be noted that Berry was decided four years before Young by a unanimous Supreme Court. There was no intimation in any intervening decision that the jury instruction validated in Berry was judicially suspect or ripe for reappraisal. Moreover, it' seems likely that the Berry instruction was probably a variant of a widely used pattern jury instruction. Thus, the Court’s decision in Young undoubtedly came as a surprise to *637 Indiana’s.trial judges; there is no way they- ctiuld.have, anticipated it.
Retroactive application of the Young rule would entail post-conviction review of a large number of convictions, many of which could have occurred over ten years ago. The mere lapse of time between the finalizing of these convictions and a potential retrial resulting from retroactive application of the Young rule could impose a severe burden on prosecutorial officials. There is a real danger that the unavailability of witnesses and tangible evidence that might occur as a result of this lengthy period intervening between conviction and retrial would render the granting of a new trial tantamount to an unconditional release from custody. This would be too great a burden on the judicial system.
For the reasons stated above, we affirm the trial court’s judgment denying post-conviction relief to Berry.
